Re: Patricia 2.0 - likely the most aggressive chess engine ever made
It’s also possible to use lc0 with the small bad gyal, mean girl, etc. nets and reducing the search to 2000 to 5000 nodes. All doable on a cpu (no gpu needed). The result is much better than trying to inject blunders into an AB engine.
Fat Titz by Stockfish, the engine with the bodaciously big net. Remember: size matters. If you want to learn more about this engine just google for "Fat Titz".

Is Evil Gyal still the one with the most "sleazy human blitz" influence?

I think so. It's not a super high priority but if I remember to get around to it it's a useful and fun feature.BrendanJNorman wrote: ↑Fri Apr 05, 2024 4:34 amWill there also be multiPV analysis capabilities in the future?![]()
Imagine being able to see this girl's top 5 move choices!![]()
I also definitely have to do some eval normalization when it comes to Patricia's scores before it becomes a useful engine for actual analysis, they're all over the place right now and generally way inflated.

Re: Patricia 2.0 - likely the most aggressive chess engine ever made
First, many thanks for this engine. It's always a pleasure to see engines that can do different things, in this case having a great playing style!
But I'm having problems in Fritz GUI. After some time Patricia 2.0 crashes. And with Patricia 1.0 curiously everything works fine. No problems at all. BTW, both engines display only two moves in its PV. Do you think it's possible to [fix] improve that for the next update?

Does it crash while searching a position? If so could you give an FEN that makes Patricia crash please? Thanks so much.Damas Clásicas wrote: ↑Fri Apr 05, 2024 7:31 am First, many thanks for this engine.

And yes, support for a longer PV is indeed planned.

Re: Patricia 2.0 - likely the most aggressive chess engine ever made
Some people are talking about Patricia crashing occasionally.
If someone can reproduce a crash I would really appreciate it (for example an FEN where Patricia crashes while searching); I found a bug but don't know if it was the problem.
